We use TAdoConnection and TAdoStoredProc to retrieve and save data to/from
the database and it works fine. We use ClientDatasets for editing the
database at the front end though (ie we populate from TAdoStoredProc, the
user edits the client dataset, then we put back via TAdoStoredProcs).
I should say there is something wrong with your ADO setup if it is taking
that long for 7000 records, unless they are VERY big records.
7000 records of 2-4000 bytes each should be only a second or so (don't want
to be more accurate in my estimate without testing, been a while since I
paid much
It would also help to know where the database is in relation to the actual
client. Are you on a gigabit network, 100mbit, or a VPN running over the
internet. all these things can play a role.
I am using the SDAC component suite.. Fast, Reliable. no issues so far.

We use the TADO controls, but were possible, or where I am not being lazy,
use non DB bound controls.
However I have heard the SDAC controls are meant to be pretty good as Kyley
seems to back up. Just a bit expensive from Memory.

If ADO is slow check the type of dataset that it is opening, it may be a
dynamic cursor where as for TCLientDataSet you onlu need a quick pass
thru, remember ADO has its own client data management built in

How big are your rows? Still sounds painfully slow to me unless there are
decent sized blobs in each row.
Neven has a good point about cursor type too although I'm not sure any of
the options should be that slow. I could do some proper benchmarking if you
wanted but I know we definitely load

HI all,
In working with John on this one I did some research on available resources for
this task, and there seems to be a deafening lack of material available online.
As opposed to other Delphi related topics.

Sorry.. I forgot to add that the Disk issue was with TEMBDB growing to over
1gb.. and the VMware disk is limited in size. the Ram issue is when SQL
server sucked up all the ram and VMware only was allocated 2gb. Tembdb was
normally the issue though.

I'm sorry but I disagree. If all of those tabs are loaded then it
shouldn't be using any CPU, or a very small amount.
Firefox has security issues, just like IE.
I use both but prefer IE, it handles flash a lot better than Firefox.
Couldn't get into Chrome.
I installed Firefox on the mac but it
Hi,
I have a report from a Windows 7 user that a message from my app does not
show unless XP compatibility mode is selected.
The code that should fire is:

It is being ignored when run under normal Windows 7 default mode.
Any ideas?
I don't use
Are you sure that it is the message display that is being suppressed and not
some change in the runtime conditions that lead to your application even
attempting to display the message in the first place?

In Chrome you can find out what is using CPU for each tab, there is a task
manager.
Try the Firefox 3.6 beta
I really really would hesitate to use IE at the moment, seeing as all
versions including IE8 on Windows 7 are vulnerable to the latest China
exploit - while it affects IE6 on XP most
while it affects IE6 on XP most no versions are immune.
Scaremongering much John?

Think we solved this - its not memory - 1GB memory on the VM made no difference.
It is the size of the records being got - over 100 fields and 4000 + bytes per
record.
If we ask for fewer fields its not surprisingly an awful lot faster.
In others experience ADO is comparable in speed to other
100 fields.. That must be one mean table :)

Firstly, Have you compared the 'load time' for the query from ADO versus
Query Analyser? If they are the same (QA is odbc based) then the perf
issue is Server/Query, if not then
its the ADO, check the ADODataSet (or equiv IIRC these are all wrappers
around tha ADO Command object) ,
Only 23 Delphi developers replied. I wonder how many people there are on

Indeed, the number of people that read the questions and couldn't even
